To @ZZ whom t may concern: p

Be it known that LARTURO Cursor, a c1t1- zen of the United States, anda resident of the city of New York, in the county of New Yorkand State of New York, ave invented certain new and useful Improvements 1n The present invention relates to improvements in bottle-Stoppers, and has for its .main object to provide a simple device of this type, adapted for use with bottles in which it is necessary to dispense the content-s thereof in smallquantities and at4 frei.

quent intervals. i

Another object of the invention is to provide a bottle-stopper of the character described that can be conveniently mounted upon bottles of any` d esired type without lilith these and other objects in view,`

which will more fully appear as the nature of the invention is better understood, the

same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of t-he several parts and details of coiistruction within the scope of the appended claims, without depart-ing from the spirit or sacrificing any of the advantages of the invention.

Two of the many possible embodiments of the invention are illustrated in the accompanying drawings, in which Figure 1 is a central longitudinal section taken through a bottle-stopper constructed in accordance with the present invention, the stopper being shown enlarged to clearly dis` close the elements thereof; Fig. 2 is a section taken on line 2 2 of Fig. 1; Fig. 3 is a section taken on line 3 3 of Fig. 1; Fig. 1 is a section similar to the one shown in Fig. 1 of a modification of the invention; and Fig. 5 is a section taken on line 5-5 of Fig. 4;.

Referring now first to Figs. 1 to 3, inclusive, of the drawings, the numeral 10 indi- Cates a bottle neck, provided with a shoulder 11 around its mouth. Upon the upper end or mouth of the neck is disposed a gasket l2 of'cork or similar material, and on this gasket rests centrally an upwardly extending sleeve 13, the lower end or' which is made in the form of `a` plate member 14:, that i entends across the gasket nearly into Contact with the iiange 15 of astopper housing 16.

The upper end of the sleeve is shaped to form` a seat 17 for a ball-valve 18, made of any suitable material. The sleeve 13 is dis-A posed within a tubular valve casing 19, the

latter being closed at its upper end by a perforated head 20, while its lower end terminates in a disk 21, that bears against the plate' member 14. The stopperhousing 16 includes a tubular portion 22, drawn over the tubular valve casing 19 and snugly ttingQthe same. The flange 15` ofthe said housing is in engagement with the shoulder 11 of the'bottle neck, thereby holding the elements of the stopper in position upon the bottle.

above the valve seat, the tubular valve casing is provided with openings 23, from which lead longitudinal grooves 24 on the guter face of the valve casing up to its head The stopper housing 16 is provided upon its tubular portion 22 with exterior screwthreads 25, meshing with interior screwthreads of a cap 26.

In use, the cap 26 is removed bv unscrewing the same and the bottle inverted, whereby the ball-valve 18 is unseated and the contents of the bottle are adapted to flow through the openings 23 and grooves 211 in the valve casing, finally escaping through the open mouth ofthe stopper housing 16. When the bottle is brought back to its upright position, the valve 18 is automatically seated, closing access' to the interior of thc bottle and thus preventing impurities, etc., from entering the same. rlhe head 2O of the valve casing 19 is perforated to permit of escape of air when the valve 18 is unseated.

It will be Observed that all of the elements of the stopper are disposed outside of the bottle and can be conveniently assembled before being put in place thereon.

t ttention is also called to the fact that the stopper housingl not only serves as the inafter to be described. Into the opening.

28 is litted a conically'shaped cup member 31, having` a flange 31 around its upper edge,ysaid liange being disposed within thel recess 29 and provided with Anotchesl 32. The disk 27 is kept in place by a stopper body 32, including 'a spout 33 and a flange 34, the; latter being in engagement with the shoulder 11 upon the.I bottle neck. To lthe cup member 31 iskfastened, atits apex, a

ycup 35,`inverted in relation to the cup mem- I' ber 31.v

. When the bottle is in its upright position,

the cup member 31, acts as a valve, closing the opening 28 in they disk 27. Bv inverting the bottle, the said valve is unseated,

Y permitting liquid to flow through the openv ing.. 28,`notches 32and4 notchesy 30 into the spout 33, leaving the bottle through the latter. `The valve is automatically seated, when the bottle is brought again to its upright' position.' When 'inverting the bottle,

some of the liquid lodges 'within the eup- Vshapedfxnernber 35' and thereby aids in un seating thevalve 31. v

A bottle-stopper, comprising `a tubular valve chamber closed at its upper end by a perforated head and Vhaving'i'ntermediate its ends ports from which lead longitudinal grooves upon the outer lface of said chambei' to its head, a sleeve fitted into said Valve chamber provided below said ports with a Signed atNew York, in the county of f New York and State of New York, this 12th day of July A.
